Injection Waterproofing:
Crack Injection: The Engineering Solution for Leak Repair & Structural Strengthening
Cracks in concrete walls and ceilings are more than just a visual defect; they are pathways for water penetration and reinforcement steel corrosion. At Taj Al Rahmah, we provide professional Crack Injection services using the latest technologies and advanced chemical materials to treat cracks from within, restoring the structural integrity of the building.
What is Crack Injection?
It is a specialized engineering process that involves pumping high-performance chemical resins (such as Epoxy or Polyurethane) under high pressure into concrete cracks. These materials penetrate the finest pores to completely fill the void, creating a watertight seal and a powerful bond that restores concrete cohesion.
Our Injection Specialties
1. Polyurethane Injection for Active Leaks (PU Injection)
Used specifically where there is active water leakage (e.g., in basements, swimming pools, and water tanks). The Polyurethane reacts with water, expanding into a dense foam that seals the leak source instantly.
2. Epoxy Injection for Structural Strengthening
Ideal for dry cracks that affect the building's load-bearing capacity. Epoxy features a tensile and bonding strength superior to the concrete itself, restoring structural rigidity and preventing future crack propagation.
3. Expansion Joint Repair & Treatment
We offer integrated solutions for injecting and treating leaking expansion joints, ensuring the necessary movement flexibility while providing total protection against water infiltration.
Why is Taj Al Rahmah's Injection Service Essential?
FeatureBenefitNo DemolitionWe treat the problem from within without the need to break walls or remove decor, saving both time and cost.Root-Cause SolutionThe injected material reaches the full depth of the concrete pour, treating the core issue rather than just the surface.Rebar ProtectionPrevents moisture and salts from reaching the steel reinforcement, protecting it from rust and deterioration.Precision ExecutionWe use advanced high-pressure pumps that ensure the crack is filled from start to finish.
Our Professional Process
-
Inspection & Diagnosis: Examining the type of crack (structural vs. hairline) to determine the most suitable injection material.
-
Packer Installation: Drilling small holes along the crack and precisely fixing metal injection ports (packers).
-
Injection Process: Pumping the material under controlled pressure until the excess emerges from the next port, ensuring a complete fill.
-
Closing & Finishing: Removing the packers and sealing the holes with specialized non-shrink cementitious materials to restore the surface's original appearance.
